Answer: Option (c) is the correct answer.
Explanation:
Wind circulation is defined as the flow of air from one place to another. This occurs due to uneven heating of air as increase in temperature raises the kinetic energy of molecules. As a result, warm air moves more rapidly.
Whereas in cold air molecules do not have enough kinetic energy. Hence, they move at slow speed.
Therefore, we can conclude that the main reason for wind or air circulation is uneven heat distribution.
